When it comes to movies it's kind of the same thing. All the movies that I saw as a kid that messed with my head ended up being my favorite kind of stuff a few years later.
Almost the same. Although I liked them a lot when I watched them the first time. The Alien Trilogy. Both Predator movies. Nothing like seeing Texas Chainsaw Massacre when you're 9. God Bless video rental store clerks who didn't give a shit.
I think I found out about them in maybe 7th grade from a guy who worked for my mother. Same guy who introduced me to The Butthole Surfers and Napalm Death and The Melvins.
I was 11 it was Empire Records. I watched that movie half a dozen times at that age. and watched it again about 6 years later, and realized just how much it influenced my mannerisms...motherfucker now I want to watch it again.
I discovered GWAR really late in life. 20
I discovered a lot of cool stuff thanks to people talking about 80's/90's punk on the internet.
It's pretty much my only social exposure. :(
